"Aarogya Setu" phone app
What is the latest status on the "Aarogya Setu" phone app for international visitors to India? Is it mandatory to have the app loaded and working before boarding a flight and upon arrival? What happens if the passenger does not have a valid cell connection or not SIM card that works in India? What happens if the passenger has multiple phones, only one of which has this app loaded? I understand that this question is moot right now since international flights are not operational yet, but I wanted to plan ahead!
